I am trying to have Firefox show an "X" on every tab as soon as I hover above it. I followed a certain article and implemented this code:

/* Show Tab Close buttons only when hovered */

  1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]) > .tab-stack > .tab-content > .tab-close-button {
 visibility: collapse !important;
 opacity: 0 !important;
 transition: all 250ms ease-in-out !important;

}

  1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]):hover > .tab-stack > .tab-content > .tab-close-button {
 visibility: visible !important;
 opacity: 1 !important;
 transition: all 250ms ease-in-out !important;;

}

  1. tabbrowser-tabs > .tabbrowser-tab:not([pinned="true"]) > .tab-stack > .tab-content > .tab-close-button {
 display: -moz-box !important;

}


This code is however not being implemented no matter how many times I restart Firefox. 'toolkit.legacyUserProfileCustomizations.stylesheets' is set to True The location is userChrome.css is '/home/user1/.mozilla/firefox/yqomjsh9.default-release-1672744596809/chrome/userChrome.css'

What could be the issue? I tried adding executable permissions using "chmod" but that did not change anything.

Try to keep the code simple and do not try to add all nodes (you missed #tabbrowser-arrowscrollbox).

/* Show Tab Close buttons only when hovered */
#tabbrowser-tabs .tabbrowser-tab:not([pinned]) .tab-close-button {
  visibility: collapse !important;
  opacity: 0 !important;
  transition: all 250ms ease-in-out !important;
}
#tabbrowser-tabs .tabbrowser-tab:not([pinned]):hover .tab-close-button {
  visibility: visible !important;
  opacity: 1 !important;
  transition: all 250ms ease-in-out !important;;
}
#tabbrowser-tabs .tabbrowser-tab:not([pinned]) .tab-close-button {
  /* only use one of these */
  display: -moz-box !important; /*xx-112*/
  display: inline-flex !important; /*113+*/
}

/* TAB: close button colors on hover */
.tab-close-button:hover {
  background-color: rgba(255,0,0,.7) !important;
  fill: white !important;
}

People are still welcome to try and get help with userChrome.css edits here as there are some people familiar with such here.
